Definitely not. -55 degrees C suggests a broken or unconnected thermal
sensor.

-2 degrees C indeed doesn't look very reasonable.

My guess would be that only temp3 is relevant on your system and that
would be the CPU temperature. This would result in the following lines
in sensors3.conf:

   ignore temp1
   ignore temp2
   label  temp3  "CPU Temp"

How many temperatures are displayed by your BIOS?

It's not inverted, it's just wrong, most probably because there's no
sensor connected to the input.
